I need advice.
I am learning a language which appears as sub-tiles.
When the meaning of the word is not known to point I would like to point at it ans ask my wife what it means.
Now, before I proceed to point the Laser pointer which is RED in color at the Plasma TV screen, I like to clear with those who are technically knowledgeable as to wether such an action will dangerous and spoil the plasma TV over time and if it is possible what is the maximum time duration I can point at the word before I switch off the pointer.
Thank you for advice.

Having worked for a laser manufacturer I am familiar with the wavelength and characteristics of diode lasers but only passingly familiar with plasma twisting technology. However it seems to me that whether the laser pointer affects the plasma or not (I would guess that it would have no effect, the only danger with plasma is undervoltage conditions or burn in from static images) it is an unsafe practice to shine a red diode at a reflective surface. You risk severe eye damage or even blindness. I believe that there are LED light dot pointers (in various colors) available at low cost that would serve as a safe pointer.
What do you mean by : ".....undervoltage conditions or burn in from static images.."
Do you mean that if I PAUSE/STILL an picture from a DVD on from the TV itself then there is a danger to the plasma ?
"it is an unsafe practice to shine a red diode at a reflective surface. You risk severe eye damage or even blindness" Point taken.
I believe that there are LED light dot pointers (in various colors) available at low cost that would serve as a safe pointer" ...Are you saying these LED pointers are safe not only for the Plasma but also for the Eyes from reflection/direct. Your further advice please .
My Laser pointer specification : Laser Diode , Wavelength 635-680 nm, Maximum Outpur lexx than 3mW , Class 2 Laser product. --What do these all mean if you care to clarify for the benefit of the uninitiated.
Thank you very much.

A laser emits coherent light. The "waves" are synchronized.
LEDs (ordinary, not laser) emit incoherent light, like a flashlight with an incandescent bulb.
